Choosing a VPS Operating System: Ubuntu, Debian or Something Else

The first decision on a new VPS is which operating system to install. For most users the answer converges quickly — here are direct recommendations and the reasoning behind them.

Beginners: just pick Ubuntu LTS

Ubuntu LTS (Long Term Support) releases ship every two years with five years of security updates. Its biggest advantage is documentation: tutorials, error-message search results and AI assistant answers almost all assume Ubuntu by default. Installing Docker, Node.js, Python or a control panel is a one-liner. Choose the latest LTS release.

For stability and minimalism: Debian

Debian is Ubuntu's upstream — more conservative packages, a leaner default install and lower memory usage. It suits long-running production services you do not want to touch often. On small VPS plans (1 GB RAM or less), Debian runs noticeably lighter than Ubuntu.

The CentOS era is over

CentOS 8 is end-of-life, and the CentOS commands in old tutorials (yum, firewalld) are no longer worth learning first. If your workload depends on the Red Hat ecosystem, Rocky Linux or AlmaLinux are the replacements — but for new projects there is rarely a reason to start there.

When to use Windows Server

Only when your workload explicitly requires Windows (legacy .NET Framework apps, certain desktop-style automation software). Note that Windows itself consumes 2 GB+ of RAM — it will not run well on a 1-core/1GB plan; choose at least 2 cores / 4 GB.

First steps after installing

Whatever you choose, do three things right after boot: apply system updates, create a regular user and disable root password login, and configure the firewall to allow only the ports you need. These three steps block the vast majority of automated attacks.
